I'm a big fan of weighing things instead of measuring with a cup. Especially with things that need to be mashed, it seems a better way of handling them since I can measure them in whole and then crush them.
crushed raspberries weigh about 230 grams for 1 cup
Couldn't find it accurate on-line so I measured it myself.
Guessing about the same for strawberries but was advised 166 g per cup. I'll measure it out again.
A flat of raspberries - with half pints - will make two batches of jam and a couple of pints left over for eating.
